IBM System/360 Model 20 The IBM System/360 Model 20 is the smallest member of the IBM System/360 family announced in November 1964. The Model 20 supports only a subset of the System/360 instruction set, with binary numbers limited to 16 bits and no floating point. In ...

and peripherals for use as a dedicated terminal.

Standard components

The 2922-1 Terminal Control Unit (RPQ 810563) employed the same instruction set architecture as the Model 20. It incorporated 8,192 bytes of 3.6 μs

magnetic-core memory Magnetic-core memory was the predominant form of random-access computer memory for 20 years between about 1955 and 1975. Such memory is often just called core memory, or, informally, core. Core memory uses toroids (rings) of a hard magneti ...

. The control unit also contained the Binary Synchronous Communications Adapter (BSCA) integrated into the Terminal Control Unit that supported a single line at speeds up to 7200 bits per second (bps). The 2922-2 Terminal Printer (RPQ 810564) was a repackaged 1403 printer. The printer used a print chain and provided a page width of 132 characters using fanfold paper. The controls and indicators for the printer were located on the front panel of the Terminal Control Unit, except for a duplicate ''start'' key on the rear of the printer. The 2922-3 Terminal Card Reader (RPQ 810565) was a repackaged 2501, an optical

reader for 80-column cards with a rated speed of 500 cards per minute. The controls and indicators for the card reader were located on the front panel of the Terminal Control Unit.

Optional components

One IBM 2152 printer/keyboard could be attached to an adapter in the Terminal Control Unit. This device had a selectric print mechanism and resembled the 1052 printer/keyboard used as a console on many System/360 computers. It operated at 15.5 characters per second (CPS). One

IBM 1442 IBM 1442 is a combination IBM card reader and card punch. It reads and punches 80-column IBM-format punched cards and is used on the IBM 1440, the IBM 1130, the IBM 1800 and System/360 and is an option on the IBM System/3. Overview The 1442 c ...

Model 5 card punch could be attached to an adapter in the Terminal Control Unit. The 1442 could punch 80-column cards at a rate of 91 cards per minute (cpm) if all 80 columns were punched.

Software

The 2922 had no disk, however magnetic core had the property of retaining programs loaded from cards thru power on-off cycles. IBM supplied a remote job entry program for the 2922 as ''Type 2'' ''Field Developed Program (FDP)''.

Users

In 1974 ''Computerworld'' reported that the State of Mississippi was using six 2922 terminals to communicate with a central System/370 Model 145.
